White in the corner?

According to the record from Neostone, this position is from 2002-10-28, Yun Chun Ho? 9d (W) vs. Kim Seung-chun 7p (B).

Is White alive in the corner ?


Lucky I cannot believe a pro could get this wrong: maybe it was a blind spot.

-- Oops. I meant that White lives with tenuki. Black said that Black cannot kill White even if Black plays first.

White lives (8 at 3)

W1 is the answer, it causes Black shortage of liberties. B2 looks like a vital point but it doesn't work.

Continuation

White is alive.
